This temperature is called the critical temperature. Superconductors are materials that have been cooled to below their critical temperature and have no electrical resistance. This means that they can carry an electric current without any loss of energy. Superconductors are used in a variety of applications, including MRI machines, particle accelerators, and power transmission lines.<\/p>\n<p>Option A is incorrect because the resistance of a superconductor decreases with temperature. Option B is incorrect because the resistance of a superconductor does not change with temperature. Option C is incorrect because the resistance of a superconductor becomes zero at very low temperature.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[amp_mcq option1=&#8221;increases with temperature&#8221;
